1/14 Skinfold thickness

Methods Skinfolds: Triceps, scapular, supra-iliac, abdominal, thigh Fat mass derived from sum of skinfolds, or by formula Limitations Inadequate norms and formulae Inter-observer variability Extremes of age and obesity lead to underestimation of fat mass

2/14 Bioelectrical Impedance Analysis

The whole body can be considered an electrical circuit with known sections.

3/14 BIA - Basic principle

From the modelling of the whole body, we can derive body composition parameters. Fat free mass = K1 x K2 x W x P x L2 / Z K1, K2 = constants; W = specific electrical conductivity P = density BIA - Basic principle

9/14 HIV-related cachexia (« Slim disease »)

The patient was a hemophiliac, infected in 1980. He developed incoercible diarrhea due to cryptosporidiosis, and CMV colitis.
